Introduction
Important
Before beginning construction of your Ultra Stick™40, decide which wing configuration is best for you—the conventional two-aileron
version or the quad flap version with two ailerons and two flaps.
With the conventional two-aileron wing, the Ultra Stick 40 is an outstanding sport aircraft. This configuration offers excellent slow
speed and stall characteristics that allow even inexperienced pilots to feel at home. Plus, it offers aerobatic capabilities that will have
your flying buddies drooling. If you’re using a 4- or 5-channel non-computer radio, the conventional two-aileron version is your best
choice.
To get the most out of your Ultra Stick 40, we strongly suggest using a 6- to 10-channel computer radio and building the quad flap
wing configuration. If you’re relatively new to flying or aren’t totally confident about your abilities, don’t let the quad flaps scare you
off. Quad flaps can actually make your Ultra Stick 40 easier to fly!
Quad flaps allow your Ultra Stick 40 to perform in many amazing ways that just aren’t possible with an ailerons-only equipped air-
plane. With a little practice, you’ll be able to use crow mixing to do amazingly short landings from high altitudes. You’ll do takeoffs
within the length of the fuselage with takeoff flaps, high speed rolls with aileron-to-flap mixing, and super-tight loops with elevator-
to-flap mixing. Plus, you’ll have fun learning about your computer radio and its capabilities.
Don’t miss out on all the possible fun. Build your Ultra Stick 40 in the quad/flap configuration. If you’re a bit intimidated about all of
that programming complication, we’ve provided an easy-to-follow programming guide in the back of this manual that will walk you
through every step of the way. Whether you own a JR 6-, 7-, 8-, or 10-channel computer radio or a Futaba 8, step-by-step instruc-
tions make programming easy!

Section 1: Assembling the Wing
Conventional Aileron
• Right wing panel with aileron and hinges
• Left wing panel with aileron and hinges
• Instant thin CA glue
• CA remover/debonder
• Paper towels
• T-pins (one for each hinge)
• Sealing iron
• White Goldberg UltraCote®
• Hobby knife w/#11 blade

Before construction begins, decide what style of wing is desired
(conventional or quad flap) and what type of engine will be
mounted on the model. The conventional aileron wing will be
presented in this section. Each aileron will be controlled by its
own servo. You will need two servos when you begin Section 3.
For a standard wing configuration, we recommend a servo
that has 40 oz/in of torque or greater, such as the JR 537 servo
that now comes standard with JR radio systems. The JR 531 or
JR 8101 are also excellent servos to use for aileron servos in
the wing.
Step 1. Carefully remove one of the wing panels from its
protective plastic. Save the plastic, as it will be used later in
Section 2 to protect the wing panel surface from epoxy smears.
Remove the aileron from the wing panel.
Step 2. Locate the hinges included and place a T-pin in the
center’s outside edge of each hinge. Slide a hinge into the hinge
slot of each wing panel until the T-pin is snug against the wing.
Step 3. Slide the aileron onto the wing until there is only a
slight gap. The hinge is now centered on the wing panel and
aileron. Remove the T-pin and snug the aileron against the wing
panel. This will ensure that the hinges are centered.
Step 4. Deflect the aileron and completely saturate the hinge
with thin CA glue. The aileron’s front surface should lightly
contact the wing during this procedure. Ideally, when the hinge
is glued in place, a 1/ 32 " gap or less will be maintained
throughout the length of the aileron. The hinge is constructed of
a special material that allows the CA to wick or penetrate and
distribute throughout the hinge, securely bonding it to the
wood structure.
Parts Needed Tools and Adhesives Needed

Section 1: Assembling the Wing
Step 5. Turn the wing panel over and deflect the aileron in the
opposite direction from the opposite side. Apply thin CA glue to
each aileron hinge, making sure the CA penetrates into both the
aileron and the wing.
Step 6. Using CA remover/debonder and a paper towel, remove
any excess CA glue that may have accumulated on the wing or
in the aileron hinge area.
Step 7. Repeat this process with the other wing panel, securely
hinging the aileron in place.
Step 8. After both ailerons are securely hinged, firmly grasp the
wing and aileron to check that the hinges are securely glued and
cannot be pulled apart. To do this, apply medium pressure while
trying separating the aileron from the wing, using caution to be
certain you don’t crush the wing structure. Move the aileron up
and down several times to "work in" the hinges and check for
proper movement.

Sealing the Hinge Gaps
Although not mandatory, it is always a good practice to seal the
hinge gap of the aileron control surfaces. Sealing the hinge line
has several advantages. A sealed hinge line gives a greater con-
trol response for a given control deflection. It also offers more
precise, consistent control response and makes trimming the
aircraft during flight easier.
Step 9. To seal the aileron hinge line, cut a piece of Clear
(GBG887) or White Goldberg UltraCote®(GBG870, not included)
approximately 3" wide by the length of your hinge line. Fold the
UltraCote®down the center with the adhesive side to the outside
making a sharp crease at the fold line.
Step 10. Measure 3/8" from the folded crease out. Make
several marks along the length of the folded covering.
Step 11. With the piece of covering still folded, use a hobby
knife with a sharp #11 blade and a straight edge to carefully cut
the entire length of the covering at the marks you made in the
previous step.
Step 12. Remove the backing from the covering. Place the
folded crease into the center of the hinge line on the bottom of
the wing. Using a straight edge, hold one side of the covering in
place while ironing down the opposite side with a sealing iron.
Step 13. Fully deflect the aileron in the up position. Place the
straight edge over the hinge line covering what you just ironed
down. With the straight edge placed firmly at the bottom of the
hinge line, iron down the covering while making sure the aileron
is fully deflected.

Section 1a: Assembling the Wing
Quad Flap Wing
• Right wing panel with aileron and hinges
• Left wing panel with aileron and hinges
• Right wing aileron/flap
• Left wing aileron/flap
• Instant thin CA glue
• CA remover/debonder
• Paper towels
• T-pins (one for each hinge)
• Sealing iron
• White Goldberg UltraCote®
• Hobby Knife w/#11 blade
• Straight edge
• Ruler
Note: The procedure for hinging the flap/aileron in
each wing panel is the same as described for the
conventional wing.
Step 1a. Locate the plastic bag containing the flap/aileron
pieces for each wing panel and remove from the package.
Carefully remove one of the wing panels from the protective
plastic bag. Save the plastic bag for use in Section 2. Remove
the conventional aileron from the wing panel.
Step 2a. The Ultra Stick 40 comes with high-quality CA type
hinges. Locate the CA hinges included and place a T-pin into
the outside edge of each hinge. Be sure the hinge remains
centered while installed into the control surface. Slide a hinge
(with T-pin) into the flap control surface, and then do the same
for the aileron control surface. When you’re satisfied each hinge
is centered, proceed to the next step.
Step 3a. Slide the aileron and flap control surface onto the
wing panel until there’s only a slight gap (approximately 1/32").
The hinges are now centered on the wing panel and the control
surfaces. Remove the T-pins and snug each control surface to
the wing panel. This will ensure the hinges are centered. Make
one more up-and-down movement of each control surface to
make sure there is no binding to the wing panel or to each
control surface.
Note: Before applying CA, make sure the flap and aileron
move freely without binding on the wing or with
each other.
Step 4a. Deflect the aileron and/or flap and completely saturate
each hinge with thin CA glue. The front control surface should
lightly contact the wing during this procedure. The hinge is
made of a special material that allows the CA to penetrate and
distribute throughout the hinge, securely bonding it to the wood
structure.
Step 5a. Turn the wing panel over and deflect the aileron
and/or flap in the opposite direction. Apply thin CA to each
hinge, making sure the CA penetrates into both the control
surface and the wing.

Step 6a. Using CA remover/debonder and a paper towel,
remove any excess CA glue that may have accumulated on the
wing or the aileron.
Step 7a. Repeat Steps 4a through 6a for the flap control
surface.
Step 8a. After both the aileron and flap control surfaces are
securely hinged, firmly grasp the wing and check to make sure
the flap and aileron are hinged securely to the wing by seeing
if they can be pulled out from the wing. Use medium pressure
and exercise caution to make certain that you don’t crush
the wing structure.
Note: Move the flap and aileron control surfaces up and
down several times to "work in" the hinges and check
for proper movement.
Step 9a. Repeat this process for the other wing panel, securely
hinging the flap and aileron in place.
Step 10a. To seal the aileron and flap hinge line, cut a piece of
White UltraCote®(GBG870, not included) approximately 3" wide
to the length of each hinge line. Fold the covering down the cen-
ter with the adhesive side to the outside, making a sharp crease
at the fold line.
Step 11a. Measure 3/8" at the folded crease out. Make several
marks along the length of the folded covering.

Step 12a. With the piece of covering still folded, use a hobby
knife with a sharp #11 blade and a straight edge to carefully cut
the entire length of the covering at the marks you made in the
previous step.
Step 13a. Remove the backing from the covering. Place the
folded crease into the center of the hinge line on the bottom of
the wing. Using a straight edge, hold one side of the covering in
place while ironing down the opposite side with a sealing iron.
Step 14a. Fully deflect the aileron and/or flap in the up posi-
tion. Place the straight edge over the hinge line covering that
you just ironed down. With the straight edge placed firmly at the
bottom of the hinge line, iron down the covering while making
sure the aileron and/or flap are fully deflected.

• Plastic wing bags (optional)
• Wing joiner brace
• 30-minute epoxy
• Epoxy brush
• Mixing stick
• T-pin
• Masking tape
• Hobby knife
• Rubbing alcohol
• Paper towels
• Wax paper
• Ruler
• Pencil
Step 1. Locate the wing joiner. Using a ruler, determine the
center of the brace and mark it with a pencil.
Step 2. Trial fit the wing joiner into one of the wing panels. It
should insert smoothly up to the center line marked in Step 1.
Now slide the other wing panel onto the wing joiner until the
wing panels meet. If the fit is overly tight, it may be necessary to
sand the wing joiner.
Step 3. The Ultra Stick 40TM is designed with "0" dihedral. Place
the wing on a large flat surface. The thickest section of the wing
should be flat on the work surface.
Step 4. Separate the wing halves and remove the wing joiner.
Once you’re satisfied with the trial fit of the wing panels, you can
prepare to epoxy the wing panels together.
Note: Use the plastic wing bags as a means of keeping
epoxy from smearing on the wings. Just slip one
on each panel and use masking tape to hold them
in place.
Important: Read through each of the remaining steps of this
section before proceeding to epoxy the wing
halves together.
Step 5. Mix approximately 1 ounce of 30-minute epoxy.
Note: It’s extremely important to use plenty of epoxy when
gluing the wing halves together.

Section 2: Joining the Wing Halves
Step 6. Place one wing half right-side-up on a flat work surface.
Note: Use wax paper underneath the wing center while the
epoxy is curing. With the wing lying flat on a surface
without any dihedral, apply more masking tape to the
wing center joint and recheck that the wing remains flat.
Also make sure the wing halves are properly aligned.
Allow the wing joint epoxy to cure completely (overnight).
Using an epoxy brush, smear a generous amount of epoxy into
the wing joiner cavity in the wing panel.
Step 7. Coat one half of the wing joiner with epoxy on both
sides, up to the pencil line drawn in Step 1. Install the epoxy-
coated half of the wing joiner into the wing joiner cavity of the
wing panel up to the marked center line. Any spilled or excess
epoxy can be cleaned up with rubbing alcohol and paper towels.
Note: Mix an additional 1-2 ounces of epoxy to complete
the wing joining process.
Step 8. Apply a generous amount of epoxy into the wing joiner
cavity of the other wing panel.
Step 9. Install a T-pin into the wing joiner at the center mark.
Next, apply epoxy to all sides of the exposed area of the wing
joiner and uniformly coat both wing roots with epoxy.
Step 10. Carefully slide the two wing halves together and firmly
press, allowing the excess epoxy to run out. Make sure the wing
panels align properly. Wipe any excess epoxy away with rubbing
alcohol and paper towels. The plastic wing bag can be removed
from the wing halves after the epoxy has been applied.
Step 11. Apply masking tape at the wing joint to hold the
wing halves together securely. Place the wing right-side-up on
a flat surface.
Step 12. Allow the wing center joint to cure completely, then
remove the masking tape.

Step 1. Locate the servo openings in the bottom of the wing.
Use a sharp hobby knife to trim away the covering over the
openings. If building the conventional wing, you will only cut
out the openings that are closest to the wing root for the aileron
servos. If you build the quad flap wing, trim away the covering
on all four servo openings in the wing. Use care not to cut away
too much of the covering.
Step 2. Install the recommended servo hardware supplied with
your radio system onto your servos (grommets and eyelets).
Install a servo extension lead to the servo as well. Secure the
connectors with either masking tape or a commercial
connector that prevents the servo lead connections from
becoming disconnected.
Hint: It’s always a good idea to secure the servo connectors
and servo extension together to prevent the wires from
becoming unplugged inside the wing. Tape works well
for this.
Step 3. Trial fit the servo into the servo opening. Depending
upon the type of servo installed, some trimming may be
required. Note that the servo is orientated so the servo arm is
closer to the trailing edge of the wing.
Step 4. With the servo in place, mark the location of the servo
screws and then remove the servo.
Step 5. Using a 1/16" drill bit, drill the servo screw locations
marked in Step 4.
Step 6. Repeat the procedure for the other servo(s). Proceed to
Step 7 before permantly securing the servos in the wing.

Step 8. Locate the two servo lead exits (oval-shaped) near the
center of the wing bottom. Using a sharp hobby knife, trim away
the covering to expose the openings, making sure to use caution
so you don’t cut into the wing sheeting.
Step 9. To thread the servo lead extensions/servo leads through
the wing, we suggest using a 24" piece of string with a weight
attached (such as one of the wheel collars in the kit). Thread it
down the servo lead opening at the root center of the wing to the
servo openings in the wing.
Step 10. Once the string is threaded though the wing, you can
get it out by reaching in the hole with needle nose pliers or let
the weight drop out of the opening by turning the wing right side
up. Tape each end to the wing to keep it from falling back into
the opening. When you’re ready to thread the servo extension
and servo lead through the wing, simply tie the string to the
extension and carefully thread them through the wing by pulling
the string/lead through the openings.
Step 11. Tape the lead to the wing to keep it from falling back
into the opening. It may be easier if you thread one servo lead at
a time.
Step 12. Securely fasten the servo in the opening with four of
the servo mounting screws supplied with your radio system. We
suggest you mark which lead is an aileron lead and which is a
flap lead. Apply masking tape to the appropriate lead and mark
either "F" for flap or "A" for aileron.
Step 13. Repeat the procedure for the other servo(s).
Note: It is intended to have each servo connected to a spe-
cific channel in the receiver. However, you can use a
Y-harness to connect two ailerons to one aileron
channel or two flaps to one flap channel, which will
require one of the flap servos to be reversed. This will
reduce your programming but also greatly reduce the
Ultra Stick™40's performance capability. Please refer
to Section 19 for computer radio programming for
the Ultra Stick 40.
Installing the linkages and control horns to the ailerons/flaps
will be addressed later in the manual.

Section 4: Bolting the Wing to the Fuselage
• Fuselage
• Wing
• Leading edge wing dowels
• Wing-bolt plate
• Wing bolts
• Drill
• Drill Bit: 1/4"
• Hobby knife
• Round file
• Flat screwdriver
• Felt-tipped pen/pencil
• Ruler (36" or tape measure)
• 6-minute epoxy
• Rubbing alcohol
• Paper towels
Note: Your Hangar 9™Ultra Stick™40 comes from the
factory with two predrilled holes in the leading edge
of the wing for the alignment dowels. You will have to
drill out the two bolt holes in the trailing edge of the
wing. First install the leading edge dowels, drill the
wing bolt holes in the trailing edge, and then install
the wing bolt plate.
Step 1. Locate the predrilled leading edge dowel holes located
on both sides of the center joint of the wing. Carefully remove
the covering from the holes with a hobby knife.
Step 2. Trial fit the leading edge wing dowels into the holes.
There should be approximately 1/2" of dowel protruding from
the leading edge of the wing. After inserting the dowels, mark
each dowel at the leading edge of wing.
Step 3. Remove the dowels and mix 6-minute epoxy. Use a
generous amount of epoxy in the leading edge holes and on the
portion of the dowels that will be inserted into the wing. Insert
dowels into the wing to the marks you previously made on the
dowels and wipe off any excess epoxy. Be sure to allow epoxy to
dry thoroughly before proceeding to the next step.
Step 4. After the epoxy has cured, trial fit the wing to the fuse-
lage by inserting the leading edge dowels into the former in front
of the wing saddle of fuselage. If wing dowel fit is too tight in the
fuselage former, carefully enlarge the holes using a round file in
the former just enough to get the wing dowels inserted.

Step 5. With the wing centered check the alignment by measur-
ing from each wing tip to the rear of the fuselage. Be sure to use
the same point on each wing tip exactly the same distance on
each side from the center of the wing. Refer to the figure below.
Step 6. With the wing centered and aligned to the fuselage,
mark the wing exactly in line with the sides of the fuselage.
Step 7. Remove the wing from the fuselage. You will use the
wing bolts installed through the bottom of the wing bolt blind
nuts to mark the location for the wing on the fuselage. In the
fuselage, locate the wing bolt block with the preinstalled blind
nuts. Partially thread the wing bolts through the blind nuts from
the bottom up until the wing bolts are just slightly above the
wing saddle.
Step 8. Carefully install the wing back onto the fuselage without
touching the wing bolts.
Step 9. With the leading edge dowels of the wing installed in
the fuselage, hold the trailing edge just above the upside down
wing bolts in the fuselage. Hold the trailing edge over the bolts,
aligning the center of the wing over the marks you previously
made on the wing. Carefully lower the trailing edge of the wing
until it contacts the wing bolts. Gently press down on the trail-
ing edge, to make indents on the bottom of the wing, marking
where to drill for the wing bolts.
Step 10. Remove the wing and the wing bolts from the fuse-
lage. Note the indents on the bottom of the wing.

Step 11. Using a 1/4" drill bit, carefully drill through the wing
at the indents in the bottom of the wing. Be careful when the drill
bit exits the top of the wing that you do not tear the covering.
Note: When you drill the wing bolt holes, be sure to drill the
holes perpendicular to the top surface of the wing.
Step 12. After you have drilled the wing for the wing bolts, trial
fit the wing into position on the fuselage. Carefully thread each
bolt just a few turns into the installed blind nuts in the fuselage.
Note: If the wing bolt holes are not perfectly aligned and you
can’t get the bolts to thread into the blind nuts, care-
fully use a round file and enlarge the hole in the wing.
It only requires that a small amount of material be
removed. The wing bolts may be hard to turn when
you first install them but will get easier in time. Be
careful not to cross-thread the bolts into the blind
nuts. Remove the wing bolts.
Step 13. Locate the wing bolt hold-down plate. Note the wing
bolt hold-down plate has holes already drilled for the wing bolts.
The holes in the wing bolt plate have the same spacing as the
preinstalled blind nuts in the fuselage. Carefully remove the cov-
ering over the predrilled openings using a sharp hobby knife.
Step 14. Insert the wing bolts through the wing bolt plate
(covered side up) and insert the bolts through the wing bolt
holes in the wing.

Step 15. Install the wing back onto the fuselage and gently
snug the wing bolts, securing the wing to the fuselage. Mark the
wing bolt plate location on top of the wing. Remove the wing
bolts and plate from the wing.
Step 16. Using a hobby knife, carefully trim away the covering
on the wing just inside the lines you marked for the wing bolt
plate. Be sure to avoid cutting into the balsa wood.
Step 17. Mix approximately 1/4 ounce of 6-minute epoxy and
glue the wing hold-down plate onto the wing. Wipe off any
excess epoxy and remove any epoxy from the wing bolt holes.
Allow the epoxy to completely cure before proceeding.
